Txheej txheem tshiab rau Recycling Magnets

Cov kws tshawb fawb ntawm Ames tshawb fawb lab tau tsim ib txoj hauv kev los zom thiab rov ua cov hlau nplaum neodymium pom ua ib feem ntawm cov khoos phis tawj pov tseg. Cov txheej txheem tau tsim los ntawm US Department of Energy's Critical Materials Institute (CMI) uas tsom mus rau cov thev naus laus zis uas ua rau kev siv cov ntaub ntawv zoo dua thiab tshem tawm cov kev xav tau ntawm cov khoom siv uas cuam tshuam rau kev xa khoom.
Ib tsab xov xwm tshaj tawm los ntawm Ames Laboratory piav qhia txog cov txheej txheem uas muab cov hlau nplaum pov tseg hard disk (HDD) rau hauv cov khoom siv hlau nplaum tshiab hauv ob peb kauj ruam. Cov txheej txheem rov ua dua tshiab no hais txog kev lag luam thiab ib puag ncig teeb meem uas feem ntau txwv tsis pub mining e-kua pov tseg rau cov khoom muaj txiaj ntsig.
Raws li Ryan Ott, tus kws tshawb fawb ntawm Ames Laboratory thiab ib tus tswv cuab ntawm CMI pab pawg tshawb fawb, "nrog rau cov khoom siv hluav taws xob uas tau muab pov tseg ntau zuj zus thoob ntiaj teb, nws ua rau kev txiav txim siab tsom mus rau qhov tseem ceeb tshaj plaws ntawm cov hlau nplaum uas muaj nuj nqis hauv ntiaj teb hauv cov dej khib nyiab. - hard disk drives, uas muaj cov khoom siv hauv nruab nrab. "
Cov kws tshawb fawb thiab cov neeg ua lag luam tau saib ntau txoj hauv kev ntawm kev rho tawm cov khoom tsis tshua muaj hauv ntiaj teb tawm ntawm e-khoom pov tseg, thiab qee qhov tau pom thawj zaug cog lus. Txawm li cas los xij, "qee qhov tsim cov khoom lag luam tsis xav tau thiab cov khoom rov qab los tseem yuav tsum tau muab tso rau hauv daim ntawv thov tshiab," Ott hais. Los ntawm kev tshem tawm ntau cov txheej txheem ua tiav raws li qhov ua tau, Ames txoj kev sim hloov pauv ntau dua ncaj qha los ntawm cov hlau nplaum pov tseg mus rau qhov khoom kawg - cov hlau nplaum tshiab.

Cov txheej txheem Magnet Reclamation tau piav qhia

Scraped HDD hlau nplaum raug sau
Txhua yam txheej tiv thaiv raug tshem tawm
Cov hlau nplaum yog crushed rau hauv hmoov
Cov tshuaj plasma yog siv los tso cov hmoov hlau nplaum rau ntawm lub substrate
Cov txheej txheej tuaj yeem sib txawv ntawm ½ mus rau 1 mm tuab
Cov khoom ntawm cov khoom siv hlau nplaum kawg yog customizable nyob ntawm kev tswj xyuas
Thaum cov khoom siv hlau nplaum tshiab tsis tuaj yeem khaws cov khoom sib nqus tshwj xeeb ntawm cov khoom qub, nws muaj peev xwm ua tiav kev lag luam xav tau rau kev xaiv kev lag luam uas qhov kev ua tau zoo ntawm cov hlau nplaum uas tsis tshua muaj lub ntiaj teb tsis tas yuav tsum tau ua, tab sis qis dua cov hlau nplaum zoo li ferrites tsis txaus. .
“Qhov kev txo cov pov tseg ntawm cov txheej txheem no yog ob zaug tiag tiag; Peb tsis tsuas yog rov siv cov hlau nplaum kawg nkaus xwb, ”Ott hais. "Peb kuj tseem txo qis cov khoom pov tseg uas tsim los ua cov hlau nplaum nyias thiab me me tawm ntawm cov ntaub ntawv loj dua.
